Key Ingredients & Substitutions
Cottage Cheese: This is the star of the dish! It adds protein and creaminess. You can use either full-fat or low-fat. If you want a different texture, I’ve used ricotta before, and it’s delightful!
Eggs: The basis of any breakfast casserole! Stick with large eggs, but if you’re looking for fewer calories or cholesterol, consider using egg whites or egg substitute. Just keep in mind that it may not be as rich.
Cheese: Cheddar is my go-to, but feel free to mix things up! Mozzarella or Monterey Jack can give a different flavor. For a lighter option, try reducing the amount or using a lower-fat cheese.
Bacon/Sausage: These are optional but add great flavor. If you’d like a vegetarian version, skip the meat and maybe add some nutritional yeast for that savory kick!
Vegetables: Bell peppers and spinach are great choices, but you can use any veggies you have! Zucchini, mushrooms, or broccoli also work well and add color.
How Do I Ensure My Casserole Sets Perfectly?
Getting the casserole just right is all about the baking time and temperature. Here are my tips:
- Check for doneness around the 35-minute mark. Insert a toothpick into the center; if it comes out clean, it’s ready!
- Make sure to let it cool for a few minutes after baking. This allows it to firm up a bit more for easier slicing.
- If you prefer a crispy top, put your casserole under the broiler for a minute or two at the end, but keep an eye on it!
Following these steps will help you achieve a perfectly set and delicious breakfast casserole every time!

How to Make High-Protein Cottage Cheese Breakfast Casserole
Ingredients You’ll Need:
Main Ingredients:
- 1 cup cottage cheese (full fat or low fat)
- 8 large eggs
- 1/2 cup shredded cheddar cheese (or your favorite cheese)
- 1/2 cup cooked bacon pieces or cooked sausage (optional)
- 1 cup diced red bell pepper
- 1/2 cup chopped spinach or kale (fresh or thawed if frozen)
- 1/4 cup chopped onion (optional)
- 1/4 cup diced tomatoes (optional)
- 1/4 cup milk or unsweetened almond milk
- 1 teaspoon garlic powder
- 1 teaspoon dried Italian herbs or mixed herbs
- Salt and pepper to taste
- Cooking spray or butter for greasing the baking dish
How Much Time Will You Need?
This recipe will take about 15 minutes for prep and then 35 to 45 minutes of baking time. In total, you should be looking at around an hour for a delicious, warming breakfast casserole!
Step-by-Step Instructions:
1. Preheat and Prepare:
Start by preheating your oven to 350°F (175°C). Grease a 9×9 inch (23×23 cm) baking dish with cooking spray or butter. This will help prevent your casserole from sticking and make it easy to serve!
2. Whisk the Wet Ingredients:
In a large bowl, whisk together the eggs, cottage cheese, milk, garlic powder, dried herbs, salt, and pepper until everything is well combined. This mixture should look nice and creamy.
3. Add the Rest:
Now it’s time to mix in the fun stuff! Stir in the shredded cheese, cooked bacon or sausage (if you’re using it), diced bell pepper, spinach, onion, and tomatoes until evenly mixed. This is where the colors from the veggies will start to shine through!
4. Pour and Spread:
Carefully pour the egg mixture into your prepared baking dish, making sure to spread it out evenly so it cooks uniformly throughout.
5. Bake to Perfection:
Place the dish in the oven and bake uncovered for 35 to 45 minutes. Keep an eye on it! Your casserole is done when it is set in the middle and the top is lightly browned.
6. Cool and Serve:
Once baked, remove the casserole from the oven and allow it to cool for a few minutes. This lets it firm up a bit for easier slicing. Cut it into squares, serve warm, and enjoy! I love adding avocado, salsa, or hot sauce on the side for an extra kick!
This High-Protein Cottage Cheese Breakfast Casserole is perfect for meal prep and tastes great throughout the week. Enjoy your hearty and nutritious breakfast!
Can I Use Egg Whites Instead of Whole Eggs?
Absolutely! If you’re looking to reduce fat or calories, you can substitute the whole eggs with egg whites. Use about 2 egg whites for each whole egg, so you’ll need around 16 egg whites for this recipe. Just keep in mind that the texture may be a bit different.
Can I Freeze This Breakfast Casserole?
Yes, you can! After baking, allow the casserole to cool completely, then wrap it tightly in plastic wrap or aluminum foil. It can be frozen for up to three months. To reheat, simply thaw it in the fridge overnight and warm it in the oven or microwave until heated through.
What Other Vegetables Can I Add?
Feel free to get creative! You can add diced zucchini, mushrooms, or even broccoli. Just make sure to chop them finely, so they cook evenly with the rest of the casserole.
How Long Will Leftovers Last in the Fridge?
Leftovers can be stored in an airtight container in the refrigerator for up to 3 to 4 days. To reheat, warm individual portions in the microwave or reheat in the oven until heated through.
